Syd March, an employee at the Lucas clinic, sells injections of live viruses harvested from sick celebrities to obsessed fans. Biological communion – for a price. He also supplies illegal samples of these viruses to piracy groups, smuggling them from the clinic in his own body. When he becomes infected with the disease that kills super sensation Hannah Geist, Syd becomes a target for collectors and rabid fans and must now unravel the mystery surrounding her death before he suffers the same fate.

On receiving news of the official selection, Brandon Cronenberg commented, "It's an honour and a thrill to be going to Cannes. I was fortunate to connect with such weirdly great people on ANITVIRAL, and to premiere our work like this is completely exciting."

ANTIVIRAL is produced by Rhombus Media with the participation of Telefilm Canada and the OMDC. The film will be distributed by Alliance Films in Canada and in the UK by its subsidiary Momentum Pictures.
